I'm not sure if I'm seeing the same problem, but I can reproduce this
symptom with my ATI box. On my ATI box it seems the problem is that
logind hasn't noticed that my Xserver session is active, so hasn't set
up the ACLs on /dev/dri/*

(And, furthermore, if the ACLs aren't set up on /dev/dri/* at startup,
gnome-session now appears to set LIBGL_ALWAYS_SOFTWARE=1, so even if you
fix the permissions of /dev/dri/* you won't get hw accel)

** Summary changed:

- Unity doesn't start on ATI test machine (fails to find GL acceleration)
+ Unity doesn't start on ATI test machine (fails to find GL acceleration) (logind fails to track session?)
